ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a computer having a plurality of file bays in which a plurality of file units such as a hard disk drive and a CD-ROM drive can be selectively mounted and, more particularly, to the computer having a function for controlling the temperatures of the file bays.
A conventional computer having a function for controlling the temperature of a file bay provided in the computer will be explained in detail in reference to the drawings.
Referring to FIG.
5
and
FIG. 6
, a portable computer
1
of the prior art includes: a space
11
; any one of a case
12
a
to a case
12
c
detachably mounted in the space
11
; a connector
13
in the main body of the portable computer
1
; a determining circuit
14
for determining which one of the cases
12
a
to
12
c
is mounted; a control circuit
15
for controlling the rotation speed of a radiating fan
16
based on an output from the determining circuit
14
; and the radiating fan
16
.
The case
12
a
to the case
12
c
respectively include a file unit
12
a
1
to a file unit
12
c
1
.
In this description, the file unit
12
a
1
is a hard disk drive (an HHD), the file unit
12
b
1
is a floppy disk drive (an FDD), and the file unit
12
c
1
is a CD-ROM drive. The number of signal pins of the file unit is different from each other.
Each case (
12
a
to
12
c
) has a converting board (
12
a
2
to
12
c
2
) corresponding to the file unit (
12
a
1
to
12
c
1
), the file unit is connected to the converting board by the signal pins. Each of converting boards can connect to the connector
13
. The connector
13
has signal pins adaptable to the file unit having the greatest number of signal pins and a signal pin for identifying a file unit.
Next, operation of the portable computer
1
will be described below in reference to FIG.
7
.
First, one of the cases having the file unit selected by a user is mounted to the space
11
. The determining circuit
14
identifies the file unit connected to the connector
13
. Subsequently, the control circuit
15
determines the rotation speed of the radiating fan
16
based on heat generating quantities of the mounted file unit, thus actuating the radiating fan
16
.
The function for controlling the temperature of a file bay according to the above-described conventional portable computer is for the computer having a single file unit.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a computer having a function for controlling temperature of file bays optimally.
According to the present invention, a computer includes a ventilation opening in a wall of the computer, a first file bay that contains a first file unit having its own identification, a second file bay that contains a second file unit having its own identification and that is arranged near the first file bay, a fan that dissipates heat from the first and second file units and that is arranged close to the ventilation opening, a bay identifying circuit that recognizes operation assuring temperatures of the first and second file units by referring to their identifications and determines a blowing direction of the fan; and a fan control circuit that controls the blowing direction of the fan as determined by the bay identifying circuit.
